A project-based course in environmental field methods will be develmped for students in the second year of earth science programs, creating a new context for students' first encounter with more complex, and in particular, more quantitative science topics. By teaching geophysical and geochemical field methods through a sequence of in-depth studies of current environmental problems, presented in their historical and social context, we hope to keep students, especially women and minorities, in the quantitative science pipeline and make clear their own potential for such work. Students will work through in-depth environmental "case-studies", or project modules, on topics such as salt water intrusion in coastal Florida, uranium mining remediation in the Navajo Nation, and eutrophication in a Georgia estuary. Students will process a subset of the data, combine data sets, analyze and interpret the data, define limits to their interpretations, and make and justify policy decisions. The course will be built around six or seven sequential modules, with each module designed to follow a classroom introduction to the relevant field methods. We plan to add supporting materials to these modules so that they can also be used as individual case studies in environmental geology, hydrology, geophysics, and geochemistry courses, and will be in a form that can be disseminated on the WWW, CD-rom, and hardcopy. This work will be a collaborative effort by four faculty at disparate institutions (College of William and Mary, Navajo Community College, and Georgia Tech). Each of us will design one or two modules, working with undergraduates at our home institutions. We will collaboratively review and revise each module as we develop the course as a whole. Thus students will encounter a wider range of both geographic settings and cultural contexts for environmental problems than is currently found in quantitative geo-science courses.

将为地球科学课程第二年的学生开发一门基于项目的环境场方法课程，为学生第一次接触更复杂、特别是更定量的科学主题创造一个新的背景。通过对当前环境问题的一系列深入研究，结合其历史和社会背景，教授地球物理和地球化学现场方法，我们希望让学生，特别是女性和少数民族，留在定量科学领域，并明确他们自己在此类工作中的潜力。学生将进行深入的环境“案例研究”或项目模块，主题包括佛罗里达州沿海的咸水入侵、纳瓦霍族的铀矿开采修复以及佐治亚州河口的富营养化。学生将处理数据子集，组合数据集，分析和解释数据，定义其解释的限制，并制定政策决策并证明其合理性。该课程将围绕六个或七个连续模块构建，每个模块都旨在遵循相关现场方法的课堂介绍。我们计划在这些模块中添加支持材料，以便它们也可以用作环境地质学、水文学、地球物理学和地球化学课程中的个案研究，并将以可以通过WWW、CD-ROM和硬拷贝形式传播的形式使用。 这项工作将由不同机构（威廉玛丽学院、纳瓦霍社区学院和佐治亚理工学院）的四名教师共同努力。我们每个人都会与我们所在机构的本科生一起设计一两个模块。在开发整个课程时，我们将共同审查和修改每个模块。因此，与目前定量地球科学课程相比，学生将遇到更广泛的环境问题地理环境和文化背景。
